The surface area of a sphere:
A = 4 pi r^2
where pi = 3.1416
r is the radius
since diameter is given
r = d / 2
r = 16 / 2
r = 8
A = 4 pi (8^2)
A = 804 sq in is the surface area of the disco ball
Answer:
$ 17172.28
Step-by-step explanation:
Each period is 1/4 year ...in ten years there are 40 periods
Interest in decimal is .036 ..... per period this is .036/4 = .009
The FV = PV (1+i)^n FV = Future value PV = present value
FV = 12 000 ( 1 + .009)^40 =17172.28
Answer:
4-4
Step-by-step explanation:
Substitute the actual values of the points into the distance formula.
Answer:
Step-by-step explanation:
6 in to 13 ft = 9 in to x ft
6 / 13 = 9 / x.....cross multiply because this is a proportion
(6)(x) = (13)(9)
6x = 117
x = 117/6
x = 19.5 (or 19 1/2) ft <====
C * 5 = 30
Divide both sides by 5
c = 6
